Optimization of Weak Lensing Lightcone Simulations for Higher-Order Statistics in the LSST era
J. Mena-Fernández, C. Doux, J. Harnois-Déraps +9
We present a framework for generating lightcone simulations tailored to the analysis of Stage-IV cosmic shear data using Higher-Order Statistics (HOS). We revisit key design choice…
Point Correlation Functions in Galaxy Surveys: Impact of Baryonic Feedback
Avijit Bera, Joachim Harnois-Déraps, Juan Mena-Fernández +5
We investigate the impact of baryonic feedback on two-point and three-point correlation functions (2PCFs and 3PCFs hereafter, respectively) involving galaxy density fields (g) and…
Preserving Clusters in Error-Bounded Lossy Compression of Scientific Particle Data
Congrong Ren, Sheng Di, Katrin Heitmann +2
Scientific particle simulations in cosmology, molecular dynamics, and fluid dynamics produce large-scale datasets whose storage, movement, and analysis increasingly rely on lossy c…
Emulator-Based Inference of Cosmological Subgrid Models
Nesar Ramachandra, Nicholas Frontiere, Michael Buehlmann +4
The formation of structure in the Universe at large scales is dominated by gravity, with baryonic physics becoming significant at scales. To capture the impact of b…
Modeling Galaxy Formation in Cosmological Simulations with CRK-HACC
Nicholas Frontiere, J. D. Emberson, Michael Buehlmann +4
Self-consistently modeling baryonic effects in survey-scale cosmological simulations has become increasingly important as the diversity, precision, and statistical reach of modern…
Cosmological Hydrodynamics at Exascale: A Trillion-Particle Leap in Capability
Nicholas Frontiere, J. D. Emberson, Michael Buehlmann +10
Resolving the most fundamental questions in cosmology requires simulations that match the scale, fidelity, and physical complexity demanded by next-generation sky surveys. To achie…
Bayesian Deep Gaussian Processes for Correlated Functional Data: A Case Study in Cosmological Matter Power Spectra
Stephen A. Walsh, Annie S. Booth, David Higdon +3
Understanding the structure of our universe and the distribution of matter is an area of active research. As cosmological surveys grow in complexity, the development of emulators t…
Illuminating the Physics of Dark Energy with the Discovery Simulations
Gillian D. Beltz-Mohrmann, Adrian Pope, Alex Alarcon +10
In this paper, we present the Discovery simulations: a new pair of high-resolution N-body simulations motivated by the DESI Y1 BAO cosmological constraints on dark energy. The Disc…
Exploring the Core-galaxy Connection
Isabele Souza Vitório, Michael Buehlmann, Eve Kovacs +3
Halo core tracking is a novel concept designed to efficiently follow halo substructure in large simulations. We have recently developed this concept in gravity-only simulations to…
